The report reviews and evaluates a number of absorption-based SO/sub 2/ control systems and the application of these control systems to those U.S. primary copper smelters which generate weak SO/sub 2/-containing gas streams. Capital and operating cost relationships have been developed for each specific process, covering a range of gas flows and SO/sub 2/ concentrations. Separate general costs for gas pretreatment and the end-of-the-line SO/sub 2/ utilization facilities (i.e., sulfuric acid, elemental sulfur, and liquid SO/sub 2/ plants) are also provided. The 13 U.S. primary copper smelters which currently still generate weak SO/sub 2/ streams have been reviewed with reference to their current operation and active programs in hand to control or eliminate weak SO/sub 2/ streams. Appropriate SO/sub 2/ control processes have been matched with the individual smelters and related capital and operating costs have been developed from the earlier established cost relationships.
